, Application filed April 14,

which the following is a specification.

This invention relates to an improved method lot(constructing buildings in reiniorced concrete. The ob ect oi the nvention ;is to economize cost and to facilitate rapid erection.

According to this invention, concrete slabs of unit measurement dimensions are cast in forms with reii'itorcing tie wires embedded in them, and saidwvires extended through the ends of the slabs to provide means for tying the slabs to studs or standards. The horizontal edges of the slabs may be formed to lap or to inset to interlock the slabs and to make the horizontal joints weather tight.

The vertical (end) edges of the slabs are butted and all the joints are finished by grouting and pointing.

The building training is designed and erected in correspondence with the length oi? the slabs, with the object thatthe abutting 'vert'icaljoints between adjacent slabs will be located against and backed by the studs or standards. Thus, for instance, where the slabs are made in staiidard lengths oi? six feet, the studding is centered at two feet or at three feet; thereby permitting the. vertical joints to be broken in symmetrical order, as in the case of brickwork construction in stretcher or other bond.

The width (height) of the slabs may vary from one to four feet for a six foot length according to the architectural appearance sought and the height of the wall which is to be covered. All the wall lengths should be a multiple of the slab unit length, so also the wall height from plinth to plate should be a multiplejot the slab unit width. As each abuttingpair of slabs is placed in position, the abutting ends are bound to the frame stud bythe wire ties, the wires from either slab being brought round the stud and twist ed together or secured by staples or other fastening to the stud. When the wiresarc strained up by tying, they operate to draw the slabs in close to the studs or standards and to draw the slab ends close up together. The abutting ends of the slabs are nicked 1920.

on the rear v dge where the wires emerge to provldc clearance for the tie wires from abutti slab ends to cross.

A fi ed structure can, according to this method, be covered rapidly with stock slabs, so that an outer reinforced concrete shell is thus erected utilizing already prepared stock slabs. Stables, garages, and the cheaper class of buildings can thus sheeted externally very rapidly and with the greatest economy, particularly when designed on rectangular'plan to din'iensions which are multiples of the slab unit measurements.

it is necessary to have regard to the necessity oi? providing for windows and door openings and for the finishing of corners. For the erection of a building, therefore, it is required that a certain number of course closing slabs be provided, each having onethird or one-half the unit slab length acrording to whether the studs are placed at hall or third slab unit cent-cringe, but uni form in height with the standard tulllength slabs, in order that vertical. joints and openings for windows and doors may be finished c neatly by means ol an overlay of mould oi cement plaster, or by wood architraves or lining. The corners of the slabbed structure may be conveniently trowel filled and linished and moulded. to align with the slab courses, and may be curved, chamtered, or arras finish. i

instead oi? layingthe tie wires lengthwise through the slabs, the tie wires may be secured into the ends of the slabs only. leaving the intermediate portion of the slab without reinforcement. The protruding tie ends may be brought out through the rear facesot the slabs instead of through the end faces thereof, thereby enabling the slabs to set close up to the studs or standards, whilst permitting the tie wires to be drawn round same to bind the slabs to the frame structure transverselyand endwise. Two or more tie wires are used for each slab, depending upon its height, and thethickness of the slab will depend on the required stability of the building. A thickness of half an inch is ample 1 most purpo es unless a slab of large area is used, when greater thickness is desirable. The slabs may be reinforced by wire ne ing, expanded metal, or other metal structure in addition to the running wires the protruding ends of which form the ties. Wooden or metal studs or 1; Fig. :3

standards may be used as desired. and the tie wires may be embedded into notches or nicks formed in said studs at appropriate intervals, so that a flush face will be left on the inner side of the building to carry board or other lining.

The essential feature of the invention is a building slab having tie wires embedded in it and protruding from its ends, which wires are adaptetfl for securing the slab to an open frame structure.

In the accompanying drawing, Fig. 1 is an horizontal section through a stud frame wall at the corner of a building, showing slabs according to my invention set on-the studs and secured thereto by the tie ends of embedded reinforcing wires; F 2 a fragmentary vertical section at2-2 F 1g.

showing the method of making tie wire clearance in the rear corners of the slabs; Fig. l is a perspective view (on diminished scale) of one of the slabs, showing the tie ends of three reinforcing wires protruding from the slab ends; and Fig. 5 is an end elevational view showing a method of interlocking the courses of slabs on their horizontal joints.

The most economical method of moulding these slabs is to mould them serially in tiers, interleaved with non-adhesive paper. ltectangular frames are provided fitted with dowel pegs in each adapted to set into holes in the frame next above or next below, and slots are made in the end frames to accommodate the tie wires. -No. 1 frame being lain on a table and the reinforcing wires placed, the concrete is filled into the open form space contained within the frame, and the top surface striclrled off flush. The surface which may be treatec immediately with damp resisting material, next covered with a sheet of non-adhesive paper. Over this No. 2 frame is set, its register being assured by'the dowels, and the same procedure is-repeated, frame after frame till a tier of say, twelve or more slabs is thus moulded.

\Vhere it is required to form interlocking edges as shown at 101l Fig. 5, the inner vertical faces of the frame forms are grooved or ribbed to complementary section. eather laps as shown at 12 Figs. 2 and a are formed in strickling the surfaces, the adjacentform site being made of acorresponding sectionto give clearance for the lap on the slab below it in each course of the tier. The slabs are allowed to in these tier-forms, and after setting, the forms are removed and the slabsset out in the open to season, water being applied to them frequently whilst seasoning according to known practice in the making of concrete goods.

Removal of the forms is facilitated by makis a fragmentary perspective view ing theinwith detachable cornerfastenings which canbe readily opened without disturbing the contained slabs.

13 are the slabs, 14 the reinforcing wires, and 15 the extended free tie ends of said wires. 16 are the building frame studs, 17 the wire tyings, which are preferably located at the sides of the studs to leave the inside faces of the studs clear for attachment of the lining. The method of securing the tie wires to the studs at door and window openings is indicated at 18. The walls when completed with an inner lining are cellular and therefore effective for insulating the building interior against heat and cold.

What I claim as my invention and desire to secure by Letters Patent is 1. A. building element consisting of a slab having rectangularly shaped ends, binding wires protruding from the opposite ends thereof and notches on the slab adjacent the protruding wires to receive the wires from an adjoining slab as the wires act to bind the slabstogether and hold them to a supporting structure.

2. In a building structure consisting of studs and abutting slabs, wires embedded in the slabs and extending from the ends thereof and round the studs each slab 'hav ing notches to accommodate the wires from abutting slabs as they pass round the stud so that the slabs may lie close'to the studs.

3. A building wall structure consisting of studs and abutting slabs,.wires protruding from the ends of the slabs and passing round the studs to fasten the slabs to the studs, each end of the slabs. having notches to receive the wires protruding from abutting slabs as they pass round the studs.

In a building structure, studs spaced from each other, slabs engaging the studs, wires extendingfrom the ends of the slabs aroundthe studs, the wire from one. slab being joined to a wire from another slab to bind the slabs to the studs and to pull them together. i

5. In a building structure, a stud, slabs having ends abutting each other on one face of the stud, wires extending from the ends of the slabs and around the stud, each slab having notches to accommodate thewires fromthe end of an abutting slab, the wiresfromthe abutting slabs being tied round the stud to hold the slabs thereto and to each other. 7 In testimony whereof I aflix my signature 1n presence of two witnesses.
